First of all, Zombie Army 4 is free to download and play with Playstation Plus!
I started playing yesterday and I was hooked immediately.
Graphics are very nice, characters (you can choose a few, but have to buy the rest) are funny and the best thing ever: zombies move at old school zombie speed (the way they supposed to move around)
Multiplayer option is awesome! and I think the game is better to play with at least one team member. I played with a dear friend (forgot to change the settings to private and had to kick a few, I'm sorry) and it played smooth. You can play with up to 4 zombie slayers.
Downsides.. I was very annoyed with the camera angle, being slightly to the right and it made it hard to grab and open crates, I kinda got used to it after a while.
There are too many BUY options, buy weapons, buy characters, buy upgrades, buy underwear, buy buy buy...
My friend lost her awesome, upgraded weapon while looting a zombie corpse, but couldn't get her weapon back?! If you know how, email us..
